MS DOS IF and % percent - variables

I haven't done DOS in forever and can't recall the idiosyncracies with prefixing labels with %. I'm trying to write a script (others may also find it useful) to connect to ADB to a WiFi service running on my tablet.
#echo off
set def=192.168.1.21
if "%1" == "" (
echo.Please supply the IP address of the ADB server/tablet.
set /p ip=[%def%]
if %ip% == "" (
set ip=%def%
)
) else (
set ip=%1
"C:\Program Files\adt-bundle-windows-x86_64-20130219\sdk\platform-tools\adb" connect "%ip":5555
)
The script should accept an IP address on the commandline, but if none is supplied, if should prompt the operator. If nothing is entered, the printed, square bracketed default should be used.
It seems to work, except that
set ip=%def%
never executes. I think I messed up the second IF statement. I just can't get the % signs in the right place!! Does anyone remember this old black magic?
Thanks.

No need to set ip to the default if the user didn't enter anything. SET /P will preserve the existing value if the user presses Enter without typing anything. So all you need to do is set the value to the default before issuing SET /P.
Problems can occur if the user provides quotes for the arguments, and then your code adds additional quotes. It is generally safer to use "%~1" - the tilde strips any existing quotes, and then you add your own. This works if the argument is already quoted or not.
You probably should remove any existing quotes when you SET ip in your ELSE statement.
You are missing a % when you attempt to expand ip as an argument to adb. I suspect that you always want to execute the command. Your current code only executes the command if ip is provided as an argument.
I would structure the code as follows:
#echo off
setlocal
set "def=192.168.1.21"
set "ip=%~1"
if not defined ip (
set "ip=%def%"
echo Please supply the IP address of the ADB server/tablet.
set /p "ip=[%def%] "
)
"C:\Program Files\adt-bundle-windows-x86_64-20130219\sdk\platform-tools\adb" connect "%ip%:5555"

Concatenating Substition variables with strings

I am modyfying a SQLplus script that creates a user, connects to the user and creates tables and puts values in those tables. This script had a set username and password for user like the below
CONNECT store/store_password#test
However I want to replace store_password with a variable v_store_password which I have put at the start:
ACCEPT v_store_password CHAR PROMPT 'Please type in store password: ' HIDE
Basically what I tried was this:
CONNECT store/&v_store_password || #test;
The above unfortunately does not work. I read some where that a "." can be used but it doesn't work.
How to concatenate or add to Substition variables?
Also how to add numbers to these variables?
/*make a file called file.connection.txt and enter username#password#tnsname#*//* write below code into batch file*/CLSECHO TITLE Database test script (ORACLE)#echo offclsfor /f "tokens=1-5 delims=#" %%a in (file_connection.txt) do (sqlplus -l "%%a/%%b#%%c " #test.sql)
exit
I actually dicovered that I have not included the & in front of variable like below
CREATE USER store IDENTIFIED BY v_store_password;
and the "." is varables concatenation character which ends them so the solution is:
CONNECT store/&v_store_password.#test;

batch list net view and write their ip address to a variable

I basically need a script (batch) that automatically converts the users on the local network to IP addresses. What I mean is basically set every user that shows up in the command "net view" to a different variable, for example:
If I had 4 different users on the network, I would need the file to list:
1: (%1%)
2: (%2%)
3: (%3%)
4: (%4%)
So I need the script to set each user on the network to a different variable (starting at 1)
Also...
How would I set the local IP address of each computer name as a variable?
update for second part: I need to know how to set the ip address as a variable. I just need to cut out the excess stuff. If I type
ping (computername) -4
I get: well, I guess it is just easier to show you...
I think I need to use the findstr command, but I don't know.
Is this what you're looking for?
#echo off
setlocal enabledelayedexpansion
for /f "tokens=1" %%a in ('net view') do (
set comp=%%a & set comp=!comp:\\=!
for /f "tokens=2 delims=[]" %%b in (
'ping -4 !comp!'
) do (Echo !comp! - %%b)
)

table==1 was unexpected at this time batch file

I am trying to apply multiple SQL scripts to an Ingres database (using a vnode setup). The testing phase will require it done to four databases. Trying to nip this annoyance in the bud I've started a batch file but receive the error above.
Many of the solutions found suggest that the batch file will evaluate everything within a block when it starts but I cannot see the forest for the trees. I have a suspicion that the parts in :1ST and :2ND are causing the problems but they need to be done.
SQL, Batch and command window output are below
UPDATE core SET sysflag='O'
#ECHO off
SET VN1=dave
SET DB1=dbtest1
SET DB2=dbtest2
SET SQL1=open.sql
SET SQL2=open.sql
:MENU
CLS
ECHO 1 - Leave
ECHO 2 - Database1
ECHO 3 - Database2
SET /P M=Choose then press ENTER:
IF "%M%"=="1" GOTO EOF
IF "%M%"=="2" GOTO 1ST
IF "%M%"=="3" GOTO 2ND
GOTO MENU
:1ST
SET DATABASE=%VN1%::%DB1%
GOTO RUNSQL
:2ND
SET DATABASE=%VN1%::%DB2%
GOTO RUNSQL
:RUNSQL
ECHO Applying SQLs to %DATABASE%
SQL %DATABASE% < %SQL1% > log_%SQL1%.txt
PAUSE
SQL %DATABASE% < %SQL2% > log_%SQL2%.txt
PAUSE
GOTO MENU
:EOF
C:\Users\me\BUILD>IF UPDATE core SET sysflag='O'==1 GOTO EOF
You are expecting the value of %M% to have 1, 2, or 3. But somehow the value is UPDATE core. The IF statement fails because there is a space in the middle of the left value. Token delimiters like space must be escaped, or the entire string on each side should be quoted. You could change your statement to IF "%M%"=="1" GOTO EOF to eliminate the error, but it still will not give the results you want.
The SET /P statement reads the value from stdin. I assume you have not typed the value UPDATE core, but instead your input was either redirected or piped. You are feeding your script the wrong value.
You should add error handling so that the code does not fall through to :1ST if the input is not 1, 2, or 3.
You can explicitly redirect input to the console for your SET /P statement. That way it will ignore the redirected input or piped input that was provided for the batch script.
<con: SET /P "M=Choose then press ENTER: "
But something seems wrong with your whole design. If you are piping or redirecting input for the script, then it doesn't make sense to present an interactive menu of choices in a loop. What happens if the user never presses 1 to quit? Eventually the piped or redirected input will be exhausted, and then you have problems.

Batch file help needed - functions, variables and substrings

I'm trying to write a batch script for windows XP. It needs to build an IP address from ipconfig by getting the (192.168.XXX.30) XXX part of the address and supplanting it into a template. Then some fun stuff from a network shared folder.
SET _var=ipconfig |FIND "192.168"
SET _var=%_var:~25,-4%
net use z: \\192.168.%_var%.30\test_folder
... Do stuff
net use z: \DELETE
ECHO "Tasks completed"
PAUSE
At the moment I can't seem to get the result from ipconfig in to my variable, would be even better if I could get the substring from it in 1 line.
Any ideas?
The first task, per your question, is to get the IP address. To get one from www.google.com:
for /f "tokens=2 delims=[]" %f in ('ping -4 -n 1 www.google.com ^|find /i "pinging"') do echo IP=%f
Say the resulting value of IP is now 192.168.10.20. You can get the third octet of %IP% from a second FOR statement:
for /f "tokens=3 delims=." %f in ("%IP%") do echo ip3=%f
The result from the above statement, given the value of the example, would be:
ip3=10

Removing double quotes from variables in batch file creates problems with CMD environment

Can anybody help with effective and safe way of removing quotes from batch variables?
I have written a batch file which successfully imports a list of parameters %1, %2, %3 etc. and places them into named variables. Some of these parameters contain multiple words, and therefor are enclosed in double quotes.
> "Susie Jo" (%1)
> "Smith Barnes" (%2)
> "123 E. Main St." (%3)
These %variables are next placed in named variables:
> set FirstName=%1
> set LastName=%2
> set ShipAddr=%3
verification of variables is done by echo.
> echo.%FirstName%
> echo.%LastName%
> echo.%ShipAddr%
results display as
"Susie Jo"
"Smith Barnes"
"123 E. Main St."
I need to eliminate the included quotes on selected variables. For instance, FirstName and LastName are used elsewhere and must not include quotes.
In a test batch file I was successful at eliminating quotes using the ~tilde character in variables.
> set FirstName=%~1
> set LastName=%~2
I thought I had the solution, but I soon experienced unusual behavior with execution of batch files. Suddenly CMD is no recognizing long path statments. Normal execution of batch file from full path
> C:\Documents and Settings\Administrator\My Documents\Txt\batchtest\dataout.bat
returns
> 'C:\Documents' is not recognized as an internal or external command....
So it would appear that the addition of the ~tilde character to the in-coming %1 %2...%n variables has caused some change. Possibly some environment variables have been altered?
I also tried clearing quotes from within variable with various attempts using the FOR command. That seems awkward and I have been unable to learn how to accomplish this by creating a list of variable to perform the task:
something like this:
for %%g in (%FirstName% %LastName%) do (
set %%g=%%~g
set %%h=%%~h
set FirstName=%%~g
set LastName=%%h
echo.%FirstName% %LastName%
)
I think I have two issues.
My 'short and sweet' idea of inserting ~tilde in the incoming %1 %2 variables (%~1, etc) seems to have affected some settings and altered how CMD navigates long pathnames.
I'm still in search of a clean and easy way to eliminate quotes from selected named variables.
Any help for those more experienced would be most appreciated. I'm at the end of my skills here... need some guidance please!

You have an extra double quote at the end, which is adding it back to the end of the string (after removing both quotes from the string).
Input:
set widget="a very useful item"
set widget
set widget=%widget:"=%
set widget
Output:
widget="a very useful item"
widget=a very useful item
Note: To replace Double Quotes " with Single Quotes ' do the following:
set widget=%widget:"='%
Note: To replace the word "World" (not case sensitive) with BobB do the following:
set widget="Hello World!"
set widget=%widget:world=BobB%
set widget
Output:
widget="Hello BobB!"
As far as your initial question goes (save the following code to a batch file .cmd or .bat and run):
#ECHO OFF
ECHO %0
SET BathFileAndPath=%~0
ECHO %BathFileAndPath%
ECHO "%BathFileAndPath%"
ECHO %~0
ECHO %0
PAUSE
Output:
"C:\Users\Test\Documents\Batch Files\Remove Quotes.cmd"
C:\Users\Test\Documents\Batch Files\Remove Quotes.cmd
"C:\Users\Test\Documents\Batch Files\Remove Quotes.cmd"
C:\Users\Test\Documents\Batch Files\Remove Quotes.cmd
"C:\Users\Test\Documents\Batch Files\Remove Quotes.cmd"
Press any key to continue . . .
%0 is the Script Name and Path.
%1 is the first command line argument, and so on.
Your conclusion (1) sounds wrong. There must be some other factor at play.
The problem of quotes in batch file parameters is normally solved by removing the quotes with %~ and then putting them back manually where appropriate.
E.g.:
set cmd=%~1
set params=%~2 %~3
"%cmd%" %params%
Note the quotes around %cmd%. Without them, path with spaces won't work.
If you could post your entire batch code, maybe more specific answer could be made.
I usually just remove all quotes from my variables with:
set var=%var:"=%
And then apply them again wherever I need them e.g.:
echo "%var%"
Spent a lot of time trying to do this in a simple way.
After looking at FOR loop carefully, I realized I can do this with just one line of code:
FOR /F "delims=" %%I IN (%Quoted%) DO SET Unquoted=%%I
Example:
#ECHO OFF
SET Quoted="Test string"
FOR /F "delims=" %%I IN (%Quoted%) DO SET Unquoted=%%I
ECHO %Quoted%
ECHO %Unquoted%
Output:
"Test string"
Test string
The simple tilde syntax works only for removing quotation marks around the command line parameters being passed into the batch files
SET xyz=%~1
Above batch file code will set xyz to whatever value is being passed as first paramter stripping away the leading and trailing quotations (if present).
But, This simple tilde syntax will not work for other variables that were not passed in as parameters
For all other variable, you need to use expanded substitution syntax that requires you to
specify leading and lagging characters to be removed. Effectively we are instructing to remove strip away the first and the last character without looking at what it actually is.
#SET SomeFileName="Some Quoted file name"
#echo %SomeFileName% %SomeFileName:~1,-1%
If we wanted to check what the first and last character was actually quotation before removing it, we will need some extra code as follows
#SET VAR="Some Very Long Quoted String"
If aa%VAR:~0,1%%VAR:~-1%aa == aa""aa SET UNQUOTEDVAR=%VAR:~1,-1%
I learned from this link, if you are using XP or greater that this will simply work by itself:
SET params = %~1
I could not get any of the other solutions here to work on Windows 7.
To iterate over them, I did this:
FOR %%A IN (%params%) DO (
ECHO %%A
)
Note: You will only get double quotes if you pass in arguments separated by a space typically.
This sounds like a simple bug where you are using %~ somewhere where you shouldn't be. The use if %~ doesn't fundamentally change the way batch files work, it just removes quotes from the string in that single situation.
All the answers are complete. But Wanted to add one thing,
set FirstName=%~1
set LastName=%~2
This line should have worked, you needed a small change.
set "FirstName=%~1"
set "LastName=%~2"
Include the complete assignment within quotes. It will remove quotes without an issue. This is a prefered way of assignment which fixes unwanted issues with quotes in arguments.
set widget="a very useful item"
set widget
widget="a very useful item"
set widget=%widget:"=%"
set widget
set widget=a very useful item"
The trailing quote " in line 4 is adding a quote " to the string. It should be removed.
The syntax for line 4 ends with %
I thought I had the solution, but I soon experienced unusual behavior with execution of batch files. Suddenly CMD is no recognizing long path statments. Normal execution of batch file from full path
C:\Documents and Settings\Administrator\My Documents\Txt\batchtest\dataout.bat
returns
'C:\Documents' is not recognized as an internal or external command....
There's your whole problem. CMD doesn't understand spaces inside of filenames from the command line, so it thinks you're trying to pass
and Settings\Administrator\My Documents\Txt\batchtest\dataout.bat
as parameters to the
"C:\Documents"
program.
You need to quote it to run a batch file with spaces in the path:
> "C:\Documents and Settings\Administrator\My Documents\Txt\batchtest\dataout.bat"
would have worked.

Demonstrates with or without quotes reguardless of whether original parameter has quotes or not.
And if you want to test the existence of a parameter which may or may not be in quotes, put this line before the echos above:
If '%1'=='' goto yoursub
But if checking for existence of a file that may or may not have quotes then it's:
If EXIST "!1!" goto othersub
Note the use of single quotes and double quotes are different.
Azure devops sometimes uses double quoting character (") to specify string. Powershell can use single quote character (') to specify string. Naturally I wanted to have a flexibility to be able to specify parameters however I wish, so same parameter can be used from both - command line - via batch file, and as a powershell script, as any parameter, including empty value.
Quote natural thinking is to write something like this:
build.bat:
#echo off
setlocal enabledelayedexpansion
set args=%*
set args=%args:"='%
echo powershell -executionpolicy bypass "%~dpn0.ps1" %args%
endlocal
But like you can guess - this does not work out of box - if no arguments are provided to batch file so %* == empty string. args expands as no string, and next replacement notices that args is not set - and instead of replacing string - it would append extra "=' garbage to args parameter.
Solution to this was just to add extra space in first assignment.
build.bat:
#echo off
setlocal enabledelayedexpansion
set args=%*
set args=%args:"='%
echo powershell -executionpolicy bypass "%~dpn0.ps1" %args%
endlocal
After this character translation should be correct:
C:\test>build
powershell -executionpolicy bypass "C:\test.ps1"
C:\test>build aa
powershell -executionpolicy bypass "C:\test\build.ps1" aa
C:\test>build "aa"
powershell -executionpolicy bypass "C:\test\build.ps1" 'aa'
C:\test>build 'aa'
powershell -executionpolicy bypass "C:\test\build.ps1" 'aa'
